and 17 and 16 and 17 represent the side forming portions which are united to the sides of portion 15 by means of portions 18 and 19 which are bound or outlined by the scored lines 90 and 21, and by the cuts 22 to enable the portions 18 and 19 to be folded face to face upon the under side of the edges of portion 15 and to which they are preferably firmlyr glued to thereby form the sides of the extension 24 of the lid. The side sections or members 16 and 17 are designed to have paste or glue applied to the face thereof as indicated by the shading in Fig. 1, and to then be folded upon and pasted to the inner faces of side sections 16 and 17 to strengthen and reinforce the sections 16 and 17 and also toA present a rounded and finished edge in place of a cut edge where the fold is made along the scored line between sections 16 and 17 and sections 16 and 17 This pasting and folding operation is preferably done on a pasting machine. before the blank'is shipped out. The portions 16 and 17 and 16 and 17 after pasting and in the set-up position to form the lid, extend outwardly from the portion 15 at substantially right angles thereto as shown in Fig. 5, but for shipment the portions 16 and-17 and 16 and 17 preferably lie flat upon the face of the portion 15 as shown either in full or in dotted line in Fig. 2. At opposite ends of the portion 16 are portions 25 divided therefrom by scored lines 27, said portions 25 constituting a portion of the ends of the lid when folded or set-up and to connect the portion 16 to the ends of the lid section. The portion 17 is in like manner and for like purpose provided at opposite ends with portions 28 divided from portion 17 by means of scored lines 30.

The sections 31 are folded along the score lines 33 so as to come face to face against the under face of the portion 15 and to form therewith the end portions 32 of the extension. The portions 34 fold along the scored lines 35 and extend outwardly at substantially right angles from the portion 15 when the lid is folded as shown in Fig. 5, but lie preferably in the same plane with portions 15 and 31, as shown in Fig. 2, when being shipped knocked-down.

In the folded or set-up position portions 36 are folded along the scored lines 38, so as to lie face to face against the end portions 34 with a pair of portions 25 and 28 embraced and locked between the adjacent faces of, portions 34 and 36. Cuts or slots 37 are provided along a portion of the scored lines 35 and the tongues or portions 39 are provided with slits to form locking barbs or tongues 39. The tongues 39 are folded along the scored lines 40 and introduced through the cuts or slots 37 so as to lie face to face upon the inner or under side of the portion 15 and to key or lock the end and side portions of the lid seetion into position shown in Fig. 5, substantially at right angles to the portion 15. As illustrated in Figs. 6, 7, and 14 the tongues 39 are drawn through the slots 37 tightly and firmly into position whereupon the tongues 39 acting as barbs or locking members enter between the sections 31 and the section 15 so as to prevent retraction of the tongues 39 through the slots 37 except by practically tearing away the tongues 39. The effect of this locking of the tongues 39 in place is to greatly add to the strength of the boxes particularly when charged with candy, soap or other relatively heavy articles, so as to prevent the weight of the contents from distorting or unlocking the boxes, and also to prevent the boxes being crushed by the exterior pressures. In the knock-down position shown in Fig. 2, the various end portions 31, 34, 36 and 39 preferably lie in a plane With portion 15. In practice the blanks shown in Fig. 1 as soon as they have been printed and blanked outare passed endwise through a gluing or pasting machine and glue or paste indicated at 16 and 17 and at 26 by shading is applied to the portions 16 and 17 and to portions 18 and 19 or to the parts of portion 15 to be overlapped thereby and after folding sections 16 and 17 upon sections 16 and -17 the blanks are then promptly folded to the position shown in full lines Fig. 2, preferably by the pasting machine. If desired the end portions 31, 34, 36 and 37 may be folded in upon the portion 15, along the scored lines 33, before the portions 18 and 19 are glued down to portion 15, but the blanks areI preferably shipped knocked-down as shown in full line Fig. 2.

For full telescopic extension boxes, blanks for the lower or container sections, 43, similar to Figs. 1 and 2, but of slightly smaller dimensions, so as to telescope into the lid sections 42, are provided, and are folded as heretofore described for the lid sections. The side extensions 24 formed by gluing the portions 18 and 19 down upon the edges of the portion 15 serve to greatly strengthen and stiffen the respective box sections, also the interengaging folding and locking of the ends of the side portions with the end portions serve to produce firm and rigid box sections equal in strength to the stayed or non-folding box sections heretofore in use.

lVhe-re it is desired to produce shoulder boxes or partially telescopic boxes two duplicate box sections 45 and 46 are formed by folding as heretofore described from blanks such as shown in Figs. 1 and 2, of equal dimensions. A folding skeleton box frame or collar 47, shown in Fig. 3, is also provided and inserted into the container box section 46 and if desired secured thereto by employed, and such boxes may be employed for general purposes with a uniform flat color or printed design and without having an outer facing paper applied to them after being folded. For general purposes any colors, designs, trade marks, printing or engraving desired may be applied directly to the fiat blanks before folding. Where it is desired however to produce special or high grade boxes such as employed for certain grades of candies and toilet articles, many of which are highly ornamented and colored, and are designed to bear the trade marks, advertising matter and insignia of the manufacturers of their contents, it is designed thatthe boxes in knock-down condition Fig. 2, be shipped from the box manufacturer' to the manufacturer of the contents, in whose place ofbusiness the boxes are folded or set up, and are then and thereafter faced exteriorly by applying a sizing and facing sheets or strip of paper of such color, or bearing such designs printing, or engraving as may serve to, produce a pleasing and artistic effect and identify th-e contents ofthe box with the manufacturer thereof.

It is designed to print the blanks, on

one or both sides in their flat condition in a variety of solid colovs and pattern designs, and to so form the extensions as to provide smoothly rounded edges and .unbroken color at the outer extremity of the extensions, and to so match the cut edges of the blank at the corners, preferably by a miter-type of joint 22 as to avoid exposing cut edges of different color to that of the faces of the extension, and also to give the saine miterioint appearance as in the stayed type of boxes.

Vhere so desired I contemplate furnishing blanks for folding extension bores to be shipped in flat condition and folded and set up either with or without the addition of facing paper, at the factory of the box maker or at the factory of the manufacture; of the contents of the box.

It frequently happens that relatively wide boxes are required, as for instance handkerchief boxes` and in Fig. 11, l have illustrated the use of two locking tongues A50 and 5l at each end of the box in place of a single locking tongue as shown in 1. Each of said tongues 50 and 51 has slit 52 cut therein to thereby form a tonguev or barb corresponding` to the barbs o9 of Fig. 1, to lock the tongues 50 and 51 in their set-up positions. rlhe employment of two tongues 50 and 51 on relatively Wide boxes serves to better hold the members 34, 25, 28 and 36 in close contact face to face with each other. In the modification vshown in Fig. 12, which is also designed to be applied yto relatively wide boxes, a central tongue 54 is employe-d at-each end and provided with a barb v55 t0 lock it in its set-upv posi-4 tion after the tongue 54 has been inserted through the central slit 56. Also at each end ofthe blank are provided additional slits 57 and 58 in line with and at opposite sides of the slit 56, yand short projections 59 and 60 to automatically register with and resiliently and automatically enter the slits 57 and 56 as the tongue 54 is drawn home to lock the box in its set-up position.

It will be noted that while means previously employed to lock folding boxes is not adapted to the-production and locking ofrelatively shallow boxes suoli as employed as handkerchiefboxes for instance, due to want of space forthe development of locking means, my improved locking means does not require any specific depth of box-for its applicatiomand can be successfully ap` plied to exceedingly shallow boxes where required. lso that when the box is once sets up and locked 1t is practically impossible. to unlock it and return it to its knocked-down condition, and hence that it is not liable to become accidentally unlocked in use so as to lose its contents,-thereby insuring a folding box of equal strength and rigidity with the stayed boxes heretofore employed for candy, soap, and other articles of material weight.

It will also be noted that my `improved locking means provides at leasttwo unbroken thicknesses of material at each end to insure rigidity at the ends of the box while the side sections 16 and 17 in connection with the side sections 16 and 17 provide side Walls of double thickness of Inaterial thereby reinforcing the side-Walls of the box to equal rigidity with that of its ends. The box with end and side walls of double thickness and when rigidly locked in its set-up position is sufliciently rigid for all ordinary purposes, such as use for candy, shoe, and soap boxes for instance. Wiere it is desired to reinforce the bottoms and tops of the boxes to double thickness, or to improve the interior finish or appearance I provide separate sections of card-board 62 of nearly the same length as the sections 15 and of somewhat greater width, which members 62 are scored at the sides along the lines 63 and-6e. These sections 62 are adapted to be insertedinto the box and lid members after said box and lid members have been set-up, and when so inserted and pressed into contact with the inner face of the sections 15 and the exposed faces of the tongues 39, the edges 65 and 66 of said sec-v tions 62 enter beneath theedges 67 and 68 of the sections 16 and 17 as shown in Fig. 8 to firmly lock the sections 62 in position to conceal the tongues 39, and to reinforce the top and bottom of the box or either of them to double thickness. I am thus enabled to produceI folding boxes from practically the same blank of progressively different degrees of rigidity according to the service required, and to ship the blanks in the fiat condition, to be set up where required for use, and of various sizes up to suit boxes or larger if required.

The articles herein illustrated and described are capable of considerable modification without departing from the principle of my invention.
